Abstract : In radio transmission of binary data, it is often desirable to conserve bandwidth at the expense of signal power. To reduce carrier bandwidth (switching rate), M bits are used to change a parameter of the carrier, so the carrier has 2M discrete combinations of amplitude, frequency, or phase.
